Answer:
Doppler Effect works on both light and sound objects.
Explanation:
Like when a sound object moves towards you, the frequency of the sound waves increases, leading to a higher pitch.
if it moves away from you, the frequency of the sound waves decreases and the pitch comes down.
Answer:
See the explanation below.
Explanation:
A species is invasive can be spread, naturally either by the behavior of the species, or introduced accidentally or voluntarily by man.
The invasive species increases its density in the occupied area or colonizes new territories over time.
That an invasive species is harmful means that it produces significant changes in the composition, structure or processes of natural or semi-natural ecosystems, endangering native biological diversity.
Uncontrolled reproduction of this invasive species also increases the risk of control and extermination of the species, due to the acclimatization of the new species in the environment as well as possible exponential reproduction.
Answer:
The speed of the large cart after collision is 0.301 m/s.
Explanation:
Given that,
Mass of the cart,
Initial speed of the cart,
Mass of the larger cart,
Initial speed of the larger cart,
After the collision,
Final speed of the smaller cart, (as its recolis)
To find,
The speed of the large cart after collision.
Solution,
Let is the speed of the large cart after collision. It can be calculated using conservation of momentum as :
So, the speed of the large cart after collision is 0.301 m/s.
Answer:
the two gliders collide, the mobile glider will transfer a bit of time to the fixed glider, which is why it comes out with a speed that is smaller than that of the bullet glider.
Explanation:
When the two gliders collide, the mobile glider will transfer a bit of time to the fixed glider, which is why it comes out with a speed that is smaller than that of the bullet glider.
Changes can occur that the gliders unite and move with a cosecant speed less than the initial one.
The whole process must be analyzed using conservation of the moment.
